On February 24, 2025, CytomX Therapeutics, Inc. (the “Company”) received a written notice from the staff (the “Staff”) of the Listing Qualifications Department of the Nasdaq Stock Market (“Nasdaq”), notifying the Company that, for the 30 consecutive business day period between January 8, 2025 and February 21, 2025 the Company’s common stock, $0.00001 par value per share (the “Common Stock”), had not maintained a minimum bid price of $1.00 per share, required for continued listing on the Nasdaq Global Select Market pursuant to Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”). The Notice has no immediate effect on the listing of the Company’s common stock.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A) (the “Compliance Period Rule”), the Company has 180 calendar days, or until August 25, 2025 (the “Compliance Date”), to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price for the Common Stock must be at least $1.00 per share for a minimum of ten consecutive business days before the Compliance Date.

If the Company does not regain compliance with the Minimum Bid Price Requirement by the Compliance Date, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company would be required to transfer its listing to the Nasdaq Capital Market and meet the continued listing requirement for the market value of publicly held shares and all other applicable initial listing standards for the Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement, and would need to provide written notice to Nasdaq of its intention to cure the deficiency during the additional 180-day compliance period. As part of its review process, the Staff will make a determination of whether it believes the Company will be able to cure this deficiency. If it appears to the Staff that the Company will not be able to cure the deficiency or if the Company does not meet the other listing standards, then the Staff will provide written notice to the Company that its Common Stock will be subject to delisting. At that time, the Company may appeal the Staff’s delisting determination to a Nasdaq Hearing Panel. There can be no assurance that, if the Company receives a delisting notice and appeals the delisting determination by the Staff to the Hearing Panel, such appeal would be successful.

To address this issue, the Company intends to monitor the bid price of its Common Stock and take steps to increase the value of its Minimum Bid Price through implementation of its business strategy and consider its other options for regaining compliance with Minimum Bid Price Requirement.to monitor the However, the Company may not regain compliance with such requirement.
